It was bright and sunny at 11:48 a.m. Sunday when the officer saw an Acura speeding northbound on Highway 101, near where it intersects with Highway 156.

She pulled her motorcycle behind the Acura and began flashing Cod 3 emergency lights to pull the driver over. At that moment, the Acura driver slammed on his brakes and came to a complete stop in the middle of Highway 101's fast lane. He slowed from 88 mph to zero mph in seconds.

The officer swerved, trying to avoid the braking car, but it slowed so erratically she crashed into the Acura.

The motorcycle officer said she saw the driver look at her while she was on the ground. The driver sped away.

"Preliminary investigations indicate that this may have been an intentional act," CHP Officer Jaime Rios said.

The Monterey County CHP is asking for the public's help finding the silver Acura and identifying its driver. Anyone with information is encouraged to call 831-796-2160.

This big-rig truck crashed on the Highway 1-Highway 17 fishhook in Santa Cruz Monday night. Witnesses told CHP officers that the truck was traveling southbound when it "flew over the fishhook" bridge and landed on the northbound lanes.
